FALL RIVER — Even before the black car stopped, the two men told police, they knew it meant trouble for them.

So they walked, and then ran, to get away from it.

But they weren’t fast enough to escape the car or the robbers it carried, the men told police.

Police were called to North Main Street at Brownell Street at 8 p.m. Friday where two men, ages 20 and 21, told Officer Shane Galus they had just been robbed.

“They were walking down North Main Street when a vehicle pulled over and one of the occupants called to them,” said Detective Lt. Kevin Tetrault, a department spokesman. “They continued on and, at one point, started running.

“The car followed and pulled in front of them. A subject got out and told them to give them what they had in their pockets. One man also lost a chain he wore around his neck.”

The man from the car gestured to his waist as though he had a gun there, police were told. When a third man walked up and challenged him, he lifted his shirt to show the handle of a pistol in his waistband, police were told.

When the gunman got cash and the chain from the two pedestrians, he got back into a black car and the car drove away.

The robber was described as a thin white man, about 5 feet, 10 inches tall,. Police were given no further description, Tetrault said.

The two pedestrians were not injured in the incident. No arrests have been made, Tetrault said.
